Title:
AUDIO TRANSMISSION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2016/000611
Kind Code:
A1
Abstract:
Disclosed is an audio transmission circuit. The audio transmission circuit includes an audio plug, at least one acoustic component and n subunits. Each subunit includes a first connection end and a second connection end. The first connection end is connected with the second connection end in each subunit. The second connection end of a previous subunit is selectively connected with the first connection end of a next subunit. A complete headset function is achieved when the signal conduction between the audio plug and the acoustic component is implemented via the subunits. At least one subunit includes a function module for accomplishing a preset function. Selection and application of a variety of functions is realized, thus improving the integration level of an apparatus.
